The main advantage of new technology is interactivity. Dynamic illumination is _dynamic_ instead of statically baked. That has obvious environmental advantages.

Comments like yours that pixel peep screenshots miss the point. These limitations seem imperceptible to you, but are very real in terms of an artists ability to execute on their vision. Most games do not currently have multiple dynamic light sources in a scene. You can go back and play Fear on PC to see that and it's awesome - Doom 3 as well. But graphics tech optimized away from that direction (rightfully), and now we need to account for dynamic illumination and transparency. Better shadows (especially in interactive moments) is a nice bonus.
